SELF-LIGHTING GAS-BURNER.

SEECIFICATION forming part of Letters Patent No. 423,525, dated March 18, 1890` 1 Application filed April 28, 1889- Serial No. 308,307. (No model.) i

To all whom it may concern:

Be it known that I, JAMES W. LYON, of Brooklyn, county of Kings, and State of New York, have invented certain new and'useful Improvements in Self-Lighting Gas-Burners, of which the following is a full, clear, and exact description, reference being had to the accgmpanying drawings, and to the letters of reference marked thereon.

My improvements relate to that class of burnersl commonly called self-lighting gas.

burners, wherein provision is made for maintaining (when desired) a very small flame, to increase which it is only necessary to turn on the gas to any desired extent.

Among the objects of my invention are the provision or production of a burner of the class named wherein the operating parts are few and simple, easy of construction, and not liable to get out of order; wherein the auxiliary gas-channel can neither become clogged nor be closeduntil the principal channel is well opened; wherein the principal and auxiliary channels and the passage through the key are so arranged that both said channels cannot be closed at the same time, and thus the light extinguished by any rapid movementof thekey; wherein the flame (when the lightis turned down)`shall be well protected from disturbance by passing air currents, ,and wherein other advantages in. the matters of l construction, operation, and use shall be secured, as will appear from the following description:

ATo accomplish these objects, my improvements involve certain new and useful arrangements or combinations of parts and peculiarities of construction, all of which will be first fully described, and then pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure l is a View in elevation of my improved burner, showing the name-protector closed, as when the light is turned down; and Fig. 2 is a similar view showing the protector opened, as when the light is turned on full. Fig. 3 is an elevation showing the side opposite Fig. 1, and Fig. 4 a similar View showing the side opposite Fig. 2. Fig. 5 is a sectional elevation of the burner upon a iiame at right angles to the axis of the key, an d Fig. 6.asimilar view upon view of the key detached from its seat, and Figs. 8 and 9 details of modified keys.

In all the iigures'like letters ot` reference, wherever they occur, indicate corresponding parts.

A is the tip of the burner, which is preferably of lava and removable, but which may be of any character and material.

B is the body of the burner, which is prefably in one piece, embodying the seat for the tip, the key-seat,-and the threaded base for application to any burner-seat.

'Within the body ot the burner are the gas- 'channels ct, l), and c, of which ct is the supply-channel, (in this form always open,) b the principal channel, through which gas is fed when the light is turned up, and c the auxiliary channel, through which the gas must pass when the dame is turned down sufficiently. It should be observed that these channels are all in a position to be easily drilled from the exterior of the burner, and theyv are all straight and amply large to obv viate any clogging up, orto otherwise impede the desirable free flow of gas.

O is the gas-key, which is fitted to its seat in the body of the burner. It is of tapering form to insure an accurate tit, and isprovided upon the small end with a lever D, held in place by a nut d, or equivalent means, such asa pin. Chains or cords, as E E, of any length, are applied to the lever for moving the key. A suitable stop-pin or projection,

as F, prevents the lever from being turned too far in either direction, andalight spring,

a plane through said axis. Fig. 7 is a side as e, between the body B and lever D insures,

always, a firm seating of the key. A gaschannel f is formed in the key by cutting in from one side a trifie past the axis. This is best shown in Fig. 7. It affords anV abundant gasway, at the same time leaving suffi-v cient uncut stock to close the channels in the manner desired, and does not (when the channels are located in the burner, as shown) require that any additional channels be formed in the key, as is required in other forms of these self-lighting burners. mounted on the key in such relation with the channel f and with the stop F that the stock or uncut portion of: the key cannot be brought around to close the inletchannel a, and the IOO bearing-surface of the stock is of such extent that itcaniiot cover or close both channels h and c at `the same time. In other words, assumin g the Haine to be turned up completely, the channel b cannot be closed until the auxiliary channel c is fully opened, and then the Haine cannot be turned up, except by admitting gas to channel b before channel c is closed.`M Thus it will be apparent that the gas under all circumstances escapes to the tip, where it isburn ed, and a flame is always maintained ready to be turned up or turned down, according to circumstances. No sudden turning of the key can interrupt the flow of gas to any such extent as to extinguish the flame, and the flame cannot therefore be snapped out, as is a common occurrence in other burners of this class.

Instead of cutting the key as shown in Fig. 7, the gas-passage in it mightextend only a little beyond the surface for the requisite distance around'the circumference, as at j", Fig. 8. This would leave more metal in the key, but would in no way modify its operation in controlling the escape of gas. Again, instead of cutting a channel in the key, as shown in either Figs. 7 or 8,'a portion of the key might be cut away, as shown at f', Fig.

9, and the remaining stock pierced, as at f2,

same figure. Such akey, being located in the burner-body, with the channels arranged as shown, would also secure all the advantages of the previous forms shown.

The flame-protector is made in two sections G G, hinged on each side of the burner-body,

as at g g, and these sections are arranged to close about the top of the burner, as in Figs. l and 3, when the flame is turned down, and to be swung down out of the way of the flame when the latter is turned up. These sections may be wholly of metal or of any other material, and they may, if desired, be provided with mica or other transparent or semi-transparent panes, as h, through which the flame may be observed when they are closed. The top of the protector t' i is shown as inclined upwardly to direct passing air-currents above and away from the flame; but the top may be otherwise formed or altogether omitted, if desired. The sections of the protector are simultaneously operated to open and close them by links k 7a,pivoted to the sections near the hinge g on the side opposite the lever D, and at their other ends eccentrically pivoted on the key C, as at l. By this arrangement whenever the keyis turned the protector is opened or closed accordingly'` as the gas is turned on or off, the pivot Z be-v ing properly located with respect to the channel for that purpose. The sections, being made to open in the manner explained, offer no detrimental obstruction to the light, are not liable to be damaged by the flame, do not create any up or down draft by which the small flame lmay be extinguished, as in the case ot' a vertically-adjustable globe or flameprotector, and they do not require that t-he burner be elongated to accommodate any vertical movement of the protector, but rather enable me to construct the burner ywith the limits of length vof ordinary gas-burners. The links might be pivoted on lever` D. At H is a regulating-screw entering the channel @,by means of which the amount of gas passing through that channel, and thus the si ze of thesinall flame, maybe governed, as will be readily understood. l

The body of the burner is of very simple form. It does not require thatit be cast with various lugs or projections to accommodate auxiliary channels or by passes, but may be made from bar metal, the circular parts being turned, and the exterior thus leftsmooth and appropriate for use in connection with a polished chandelier or bracket.

I-Iaving thus fully described my invention, what I claim as new herein, and desire to secure by Letters Patent, is p l. In a self-lighting burner, the combination of the burner having the supply openings or passages, the key seated in the burner and having a groove adapted to communicate with said passages, the protector consisting of the two parts pivoted to the burner, the links having their upper ends connected to the protector and their lower ends pivoted together eccentrically to the key, substantially as and for the purpose described.

'2. In a self-lighting burner, the combination of the burner, the key seated in said burner, thek protector consisting of the two members pivoted at their lower ends to the burner, the links having their upper ends connected to the members of the protector near the pivot thereof, and their lower ends eccentrically connected to the key, substantially as described.A

3. In a self-lighting gas-burner, the combination of the burner, the key seated therein, the lever connected to one side of the key, the spring for retaining the key and lever, the-stop or projection on the burner for limiting the movement of the lever, the protector consisting 'of the two members having their lower ends pivoted to the burner, land the links having their upper ends connected to the members of the protector and their lower ends eccentrically connected to the key, all arranged and adapted to operate substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand in the presence of two witnesses. y
